It willrbe understood, however, that any reference to partsof the deviceinthe yterms used in describing hospital equipment shallnot constitute a limitation on modifications for other uses. y Referenceis now had to the drawingsin which the numeral l0 is employed todesignate one modication of the invention adaptable'. for `use .as apartof hospital equipment. Thecabinet includes a rectangular compartment1,1; having'a top wall l5, and bottom wallY 16. The front 'of' thecompartment is closed by afdoor 17. A, The ysides and rear of the`compartrnent ll .are formed by a reector 18 which is straight invertical section and curved in horizontal section.4 The central portionof the reiiector is formed through a Vslight curvature which increasesto form end pockets 19 adjacent Athe inwardly. directedfflanges of thetop and bottom wallsk l5 andl6. The partic-ular; curvature ofthe mainportion ofthe -re- `closure position for of a detail of l lectorrdepends on the Ysize ofthe v*compartment vbut is under allcircumstances shapedtofprovide uniform light distribution.,` Withinthepockets 19 is locatedpthe source of illumination, This illumination isprovided by two sets of lamps 20, the number of lamps in each setdepending upon the size of the cabinet and the type of film to beviewed. The lamps are mounted in sockets 21 which are secured in anyconventional manner to-the top and bottom walls 15 and 16 of thecompartment 11. Connection with all lamps is had exteriorly of thecompartment 11. `Vertical members 23 are secured along their innerflanges 24 to the forward edges of the reflector 18. These membersconstitute a partial support for vertical portions 25 of a iinish trim26. These portions are joined along ilanges 27 to the forward flanges 28of the members 23. The trim is formed with rearwardly directed ilanges29, on the inner faces of which are located spring clips 30. The topwall 15 of the compartment is formed with an upwardly directed flange32, to the forward face' of which is secured a corresponding flangeofthe upper horizontal portion 33 of the trim 26. This portion of thetrim is also provided with a return bent flange 34 having a spring clip3.5 on the inner face thereof. A lock or latching member 36 is securedto the rear face of the portion 33 of the trim being provided with adownwardly movable bolt 37. The bottom wall 16 of the compartmentterminates in `a downwardly directed flange 38 havingvone'or morehorizontal slots 39.

Beneath the compartment 11 is a compartment 40 shown to be formed by acontinuous side and rear wall 41 yand removable bottom wall 42. The sideandr rear'walls are provided, top and bottom, with horizontal flanges43V and 44 respectively, flanges 43 being welded to the underface ofwall 16 of the'container-and flanges 44 constituting a rest or supportfor the removable wall 42. The forward edges ofthe side and rear wallsterminate in flanges 45. The compartment 40, in commercial practice,will form a part of the entire cabinet and will'lieV within the trimwhich surrounds the front face of the cabinet. Consequently the trimportions 25 will be secured along the lower portions of their flanges 27to flanges 45. The upper edge of rthe horizontal portion 47 of the trim26 seats the front flange 48 of the wall 42. The portion 47 alsoincludes a springrclip 49 similar to clips 30 and 35. It will beunderstood that the elements 25, 33 and 47, which constitute the entirerectangular trim 26, are mitered and joined in any conventional manner.f Y

The compartment 40 is provided with a hollow closure 50 which, when'saidclosure is in open position, permits useof the inner face 51 as a shelfon which tolay and'sort various films. The closure 50 is pivoted on thevertical portions 26 of the trim through a hinge structure'whichincludes pins 52. Each pin 52 includes an enlarged and reduced portion53 and 54 connected by an annular shoulder 55'. The portion 54 projectsthrough ay suitable opening in the end wall of the closure to a pointvwhere the shoulder 55 abuts said wall. A U-shaped strap 56 is securedto the rear face of each of the elements 25. The base wall .57 of thestrap isdrilled and ltapped to receive avset screw 58. The portion 53 ofthe pin lies within thestrap 56 and is secured against dislodgement orrotationy byl the set screw 58.

Mounted onone of the sidewalls of the compartment 40 is an angle bracket60, the inwardly directed portion of which isformed with an opening toreceive a closure supporting rodV 61. This vrod is provided with a head62 `at one end adjacent the bracket and pivot plate'63 at the other end.The plate 63 is secured in any suitable manner to the shelf portion 51of the closure 50.

The opening in the compartment 11 is closed by the door 17 whichincludes a viewing glass, masking curtains and film clips. This doorcomprises a rectangular frame 65 having inwardly directed flanges 66. Areinforcing plate 67 is secured to the inner face of each wall of theframe 67. The lower plate 67 (see Figure 3) has attached thereto adownwardly flanged strap 68 which projects through the slot 39 in flange38 and constitutes the hinge support of the door. The upper horizontalplate 67 and the inturned flange 66 are slotted to receive the bolt 37,The viewing glass 70 is enclosed along its vertical edges by channelmembers 71. These members have extensions 72 above and below thehorizontal limits of the glass which abut the horizontal portion of thetop and bottom plates 67. A block 73 is secured within each of theextensions 72. Suitable means in the form of a screw 74 secures theblock 73 to the frame 66 and plate 67.- The upper and lower horizontaledges of the glass 70 lie within channel members 76. These memb-ers aresecured to the vertical channel membersv 71 any suitable manner as byangle f brackets 77. It is to be noted that the front edge of eachchannel member 71 andv 76 is formed with a ared portion 78. Attention isparticularly directed to the fact that the framed glass 70, being spacedinwardly of the front edge of the door frame 65, provides a Ventilatingopening which entirely circumscribes the glass. 1 VAngle plates 80 arelocated top and bottom of one of the vertical flanges 66 and havesuitable openings therein by which to receive a guide rod 81. The upperplate is provided with an upstanding block 82, the notch 83 of whichreceives the key `plate 84 of a spring roller structure 85. Thestructure`85 is without palls and-when rotated to increase the tensionof the spring, will tend immediately to rotate in the oppositedirection. The other end of the roller structure 85 consists of a shaftwhich is mounted in an upstanding flange 86 of a corresponding angleplate 87.

-Mounted on the structure 85 is an opaque masking curtain 88. The freeedge of this curtain is fitted with a bar 90,`to one end of which issecured a guide block 91. This block includes a horizontal arm 92 andupper and lower cylindrical portions 93 and 94 which are connected onone side by a strap portion 95. These cylindrical portions 93 and94`each have an opening therethrough for receiving the guide rod 81.Secured to the horizontal armr 92 is a spring plate 96 which extendsinto the vupper cylindrical portion 93 and frictionally engages the rod81. Directly beneath the portion 93 is a'forwardly directed horizontalstrap 97. Secured to this strap is a plate 98 which terminates in ahandle or knob operator 99. Examination of Figures 2 and 8 disclose thefacts that the plate 98 projects through the Ventilating opening betweenthe glass 70 and the frame 65 and the knob 99 lies adjacent the inneredge of a vertical portion ofthe frame 65. Consequently manual controlof the vertically movable curtain 88 does not interfere with themounting of films on the glass 70 nor does it block off viewing anyportion of a film on the glass.

The guide block 91, being provided with friction means in the form of aplate 96 which engages the lrod 8l, acts to counteract the upward pullof the spring roller structure through the curtain 88. This frictionalcontact of the plate 96 is not effective against manipulation oftheoperating knob 99. Consequently the curtain 88 may be extend- CFIjecting through said opening to the exteriorpf` said cabinet andservingas an operator tomove said curtain.r .u V:
